Note to Sapphire about the "Gargoyles/Buffy" crossover possibility:

While my thoughts on this one probably count less than Greg's (he's the creator of the series; I'm just one of the fans), I do think that such a crossover, while in some ways more feasible than, say, "Gargoyles/Batman" or "Gargoyles/Superman", does have a few snags to be overcome. One is legal ownership (Disney owns "Gargoyles", WB "Buffy"). Another is geography (Buffy and Co. live on the West Coast, the gargoyles on the East Coast).

(Of course, there's no danger as yet of "Gargoyles Universe" vampires being incompatible with the Buffyverse, since all that we know about "Gargoyles Universe" vampires is that they're vulnerable to silver - Princess Katharine mentions this in "Ill Met By Moonlight" - which doesn't contradict any statements about vampires in "Buffy").

But as I said, I don't view such a crossover as something all that likely for the near future, myself.
